The element represented by the symbol "N" is nitrogen. Nitrogen is a non-metal gas that constitutes about 78% of the Earth's atmosphere, making it the most abundant element in the air we breathe. It is colorless, odorless, and tasteless, playing a crucial role in various chemical processes, including the nitrogen cycle, which is vital for life on Earth. Nitrogen is also a key component of amino acids, proteins, and nucleic acids (DNA and RNA). In its elemental form, it is relatively inert, but it can form a variety of compounds, including nitrates and ammonia, which are essential for agriculture.
